SPLASH'. LUBRICATION SYSTEM.

Application led March "17, 1909. Serial No. 483,912.

To all whom it may con-cern:

Bc it known that I, CHARLES N. Tueren, a United States, residing at Hagerstown, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Splash Lubrication Systems; and I do hereby declare the following to be a full7 clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainstomake and use' the same. y

My inventionk relates tosplash lubrication systems for hydrocarbonengines.

It lia's for its object to regulate to better advantage the amount of oil through which the crank of the engine passes at each revolution.

The invention comprises an inner receptacle or pan arranged within the under bon net of the crank case in position to receive the crank onits down stroke, and means for regulating `the flow of tbe-lubricating fluid to said pan from said under bonnet proper into which it is splashed from the pan by the action of the crank.

The invention also consists in the features of construction and combinations of parts hereinafter described andk specified in the claims.

In the accompanying drawing illustrating the preferred embodiments of my inventidn: Figure 1 is a broken side elevation of the under bonnet of the crank ease of afour cylinder engine, the crank shaft and one 0f the cranks being shown. 'F ig. 2 is a cross section on the line of Fig l, and Fig. 3 is'y an enlarged broken section on the line f-fy of Fig. 1, the crank and shaft being omitted.

While I have illustrated my inventiouas applied to the crank case of a four cylinder engine, it will be understood that it may be employed with equal success in connection with the crank cases of engines having` one or any number of cylinders and cranks.

In the drawing, l designates ,the under bonnet of -the crank case which is divided into four compartments bythe ribs 2 preferably placed equidistant apart and extending to a suitable height from the bottom. The portion ofsaid bonnet extending between two adjacent ribs Vmay be termed the under bonnet proper of one of the cranks 3 onthe shaft Lt'. 'A funnel-shaped groove 5 is formed at theibottm of each of the compartment and leads to a discharge .nozzle 6 preferably the lubricating fluid may be drawn'oii inner pan 8 is arranged centrallyoi compartment and is in position to be ente by the crank on its down stroke.

, l 'l closed by a screw plug 7, iiheieoy 69. Sa'idpanr preferably conforms to the path of movef ment ofi the crank as illustrated in Figs; 7"

and .3, and is only slightly wider thantlie" l prank, as shown in Fig. l. The innerpan is preferably supported above the crankzcase and is rigidly held Ln'place upon upwardly proiecting lugs 9 and forms a bridge over the funnel-shaped groove or trough 5. I In order to permit the lubricating` iiuid lin the under bonnet proper to `pass into t-liev the sides of' which extend upto" the ribsQg inner pan, about the level of the tops of an opening` lOis formed preferably `inthe bottom of said pan.y

the bottom of fitted in said openingT and is adjustableiby c means of a thumb uut lilou its screwv threaded stein 13 which extends thi-ouch tl'ic bfltoui of the under bonnet. as shown in -Figs'. l and 3. A stalling box le is located in 'the bottoni of said bonnet to prevent the oil ufrom flowing out along the valve stein.

It will be noted that before the engine is started, the oil will seek its level in thc pan but that when the crank begins to turn and passes through said pan, it will splash the oil from it into the outer compartment. The oil niust then find its way back into the pan through the opening l0. Tlieiitnv of` 1 the oil through this opening may be regulated to suit requirements by means of the needle valve.

I' claim :#1

'1.-In a splash lubrication system, the combination, with the under bonnet of the crank case, of a pan arranged "therein in position to be entered by the crank on`the down stroke thereof, s aid pan having an opening to permit the lubricating Huid to.

enter said pau from said bonnet.

2. In a splash lubrication system, vthe combination, with the under bonnet of the crank case, of a pan arranged therein above the bottom of the bonnet in,position to be entered by the crank on the down stroke thereof, said pan having` an opening to permit the lubricating fiuid to entei said pan from said bonnet.

3. In a splash lubrication system, the combination, with the under bonnet of a crank case, of a pan arranged therein in iosition to be entered by the crank on the own stroke thereof, said pan being shaped 'to conform' to the path of movement of the crank and having an opening to permit the lubricating Huid to' enter said pan from said bonnet.

4. In a "splash lubrication system, the combination, with the under bonnet of the crank-case,`"`of a pan arranged therein above the bottom of the bonnet in position to be entered by the crank on -the down stroke thereof, Said an being Shaped to conform to the path of) movement of the crank and having an opening to permit the lubricating vfluid to enter said pan from said-bonnet.

5. In a splash lubrication system, the combination, With the under bonnet of a crank case,'of a pan arran 'ed therein in position to be entered by t e/crank on the down stroke thereof, said pan having an opening 'in its bottom to perrnit the2 lubrieating fluid to enter said i n fronrsaid `bonnet. f

` 6.- In lsplash lubrication system, the com .hi `nation,. with the under bonnet yof the f prank caae,l of a .pan-arranged therein in ositiongtobe'entered by the crank on the gown strokethereof,'sa1d pan having an opening to permit the lubricating fiuids to enter said pan from said bonnet, and means to regulate the flow through said opening.

' 7. In a splash lubrication system, the
